Medium Duty Precision Live Center
A live center is constructed so that the 60° center runs in its own bearings and is used at the non-driven or tailstock end of a
machine. It allows higher turning speeds without the need for separate lubrication, and also greater clamping pressures. CNC
lathes use this type of center almost exclusively and they may be used for general machining operations as well.
Besides, we also have medium duty carbide live center
The Heavy Duty Precision Live Center is an indispensable tool for turning long, heavy, or large-diameter workpieces on manual and CNC lathes. When taking aggressive roughing cuts, standard live centers can quickly succumb to vibration, bearing failure, or thermal expansion. Our heavy-duty models solve this by utilizing a significantly thicker body and a premium internal bearing configuration designed to absorb extreme cutting forces. Whether you are machining heavy forged steel shafts or performing high-speed finishing operations, this live center ensures your workpiece remains perfectly aligned and chatter-free.
Advanced Multi-Bearing Design: Incorporates a high-precision double-row angular contact ball bearing, a heavy-duty thrust bearing, and a needle roller bearing. This combination provides exceptional rigidity and load-carrying capacity in both radial and axial directions.
High-Speed Capability: The precision-balanced internal components and high-quality lubrication allow for sustained high-speed turning without overheating, making it ideal for modern CNC turning centers.
Superior Wear Resistance: The center point is forged from premium alloy steel (such as SUJ2) and heat-treated to HRC 60±2. This ensures long-lasting wear resistance against the rotating workpiece and maintains precise 60-degree geometry.
Advanced Waterproof Sealing: Equipped with a specialized labyrinth seal and a high-quality lip seal at the front. This dual-protection system effectively prevents cutting fluids, fine metal chips, and grinding dust from penetrating the bearing cavity, drastically extending the tool's service life.
High Concentricity: The center point is precision-ground while rotating in its own bearings after full assembly, guaranteeing a maximum Total Indicator Runout (T.I.R.) of 0.005mm (0.0002").
Direct Manufacturer Savings: Bypass trading companies and source premium lathe accessories directly from our factory for highly competitive wholesale pricing.
Comprehensive Taper Options: Available in all standard Morse Taper sizes (MT3, MT4, MT5, MT6) to fit a wide variety of machine tailstocks.
Strict Quality Control: Every live center undergoes rigorous dynamic testing for runout, load capacity, and rotational smoothness before being approved for shipment.
OEM & Customization: We offer custom laser engraving of your brand logo, part numbers, and tailored protective packaging for retail distributors and catalog companies.
Q1: How does a "Heavy Duty" live center differ from a standard one?
A: A heavy-duty live center features a larger, more robust housing and a much stronger internal bearing configuration (often using thrust and needle bearings instead of just standard ball bearings). This allows it to support significantly heavier workpieces and withstand the high axial loads generated by aggressive feed rates and deep cuts without failing.
Q2: Why is the waterproof seal important for a live center?
A: In CNC machining, high-pressure coolant is constantly spraying the cutting zone. If coolant or fine metal chips enter the live center's housing, they will quickly degrade the grease and destroy the precision bearings. Our advanced labyrinth and lip seals ensure the internal components remain clean and lubricated, maximizing the tool's lifespan.
Q3: Can this live center be used for high-speed finishing?
A: Yes. Because it utilizes high-precision angular contact bearings and is dynamically balanced, it can maintain smooth, vibration-free rotation at high RPMs, which is essential for achieving excellent surface finishes during final turning passes.
Q4: How do I maintain my live center?
A: Our heavy-duty live centers are permanently lubricated and sealed at the factory, so they are generally maintenance-free. However, you should always keep the Morse taper shank clean and free of burrs before inserting it into the tailstock, and store it in a dry, protective case when not in use to prevent accidental damage to the precision point.
